摘要
An engine fault diagnostic system includes a diagnostic module that generates a manifold absolute pressure (MAP) error signal and that generates a mass air flow (MAF) error signal. A security module generates an air flow fault when the MAP error signal exceeds a MAP threshold and the MAF error signal exceeds a MAF threshold.
